' 2 Claims. (Cl. 199-37) The present invention relates to type casting machines and more particularly to a novel means for supporting and transferring matrices vfrom an elevator head to the distributor box.

In such transfer mechanisms now in general use a second elevator head carries a V-section box bar having lengthwise parallel ribs which are shaped complementally to mesh with the ribs or teeth on the V-slot of the conventional present day matrices. Thus a matrix can be fed onto the elevator bar to be supported by the meshing ribs or teeth in position to be pushed along the box bar for transfer to the aligned bar in the distributor box. This distributor box bar, according to present practice, is like the above described elevator bar in that it is of V- section having lengthwise ribs or teeth for alignment with the teeth on the elevator bar to receive the transferred matrix.

With such construction the meeting ends of the two bars must maintain a very precise aligned relation to avoid damage to the distributor bar teeth or to the teeth orto Ithe teeth of a matrix. This -is a serious problem because such aligned relation is upset due to vibration and wear and expensive repairs have to be made of damaged parts.

An object of the present invention is to provide a matrix transfer mechanism wherein the foregoing disadvantages of toothed or grooved distributor box bars are overcome.

Another object is to provide a distributor box bar wherein the usual lengthwise guiding and supporting lengthwise teeth are replaced by plane surfaces in the path of the toothed matrix slot.

Another object is to provide a V-section distributor box bar having plane sides to receive a transferring atgx while providing a matrix support independent of e ar.

A .further object is to provide a novel distributor box bar assembly wherein the bar is of two parts mounting a bar point between in clamped position: and

To provide other improvements as will hereinafter appear.

In the accompanying drawings:

Fig. 1 is a side elevation View of a conventional grooved second elevator bar as carried by the elevator and arranged in operative alignment with the distributor box bar which forms a part of the present invention:

Fig. 2 is a plan view of the distributor -box bar with its removable elongated bar point:

Fig. 3 is an end view of the bar of Fig. 1:

Fig. 4 is an exploded View of the three part distributor box bar and bar point:

Fig. 5 is a face View of a conventional matrix: showing in section the supports therefor:

Fig. 6 is a side elevation of the back matrix supporting guide rail; and

Fig. 7 is a side elevation of the 'front matrix supporting guide ra'il.

Referring to the drawings and initially to Fig. l where the conventional elevator bar 10 is shown as carried by States Patent 2,975,886 Patented Mar. 21, 1961 the second elevator 11. The lower portion of the bar Y 10 is of \Vsection having sides in the form of lengthwise cut parallel teeth 12 for meshing with the teeth 13 in the V-slot 14 of a matrix 15. Thus the bar 10 provides a support for the matrix |15 while permitting the latter to slide lengthwise of the bar tor transfer to the distributor box which heretofore has carried a V-shaped bar with teeth for meshing and supporting the received matrix. According to the present invention the distributor box bar 16 is radically dilierent `from the foregoing described bar 10 in that while having a V-section to enter the slot -14 of the matrix its sides are respectively plane surfaces. This distributor box bar 16 is supported by the distributor box part 17 and has a transverse cut-out 18 at one end to receive the tongue 20 of the elevator ba-r 10 as a joint between the meeting ends when the second elevator swings into alignment with the distributor box.

While the box bar 16 .of the present invention may mount the bar point 21 in the conventional screw fastened manner, it -is of a preferred improved construction to make the replacement of a worn or damaged bar point far simpler and less expensive. As shown in Figs. 3 and ,4, the box bar 16 is formed by dividing it medially lengthwise into two parts 16a and 1Gb ltor the reception of the bar point 21 which extends throughout the length of the bar to be clamped between the parts by fastening screws 22 at suitable points in the length. Thus therefore the section 16a of the bar has counter-bored holes 23 for the shank and head of each screw 22 while the other section 16b has threaded holes 24 for the threaded ends of the screws 22. Registering holes '25 are provided in the point 21, so that the three parts become a complete bar unit as assembled.

To ensure proper assembly of these bar parts several transverse registering holes are provided ifor respectively receiving dowel pins 26 to accurately locate the parts when being assembled, as will be understood.

Since by the invention the conventional longitudinal grooves or teeth on the distributor box bar have been eliminated, a novel means is provided to support a matrix independently of the bar 16, such means, in the present instance, comprising a front guide rail 27 att-ached to a plate part 28 of the distributor vbox in position to enter the space between the upper laterally projecting lug 30 and lower laterally projecting lug 31 of the matrix |15, as a support and guide for that side of the matrix. The rail 27 `is xed to the box by suitable fastening means such as the threaded holes 29 for the respective reception of screws 32.

A second matrix Iguide support rail 33 is attached to a plate 34 attached to the opposite side of the distributor box in position to enter the space between the upper laterally projecing lug 35 and the lower laterally projecting lug 36 of the matrix 15 as a support and guide for that side of the matrix. Screws 37 traversing threaded holes 38 hold the rail 33 to the box plate 34.

In the present construction both support rails 27 and 33 project at one end from the distributor box so in order to permit the elevator bar strom striking the front rail 27, it has a notched corner 40 for the passage of the second elevator to its position. The top edges 41 and 42 of the respective rails lie in the same horizontal plane to serve as supporting surfaces for the uppervaligned matrix lugs 31 `and 35.

It will now be apparent that a complete novel distributor box bar assembly has been devised wherein the transfer of matrices from an elevator bar to the distributor box without the use of aligned matrix supporting teeth from one bar to another. This practically eliminates the danger of damage due to misalignment of parts and increases the life of matrices as well as the distributing bars. Also the novel assembly makes it possible to sup mounting for a bar point;v blade in association with a two part bar whereby such :bar points can 'be quickly replaced without the loss of time and expense of'present -bar point mounting.

Having now described my invention, fl claim:

1. As a new article of manufacture atype-casting'machine distributor box bar having 1a-slot extending lengthwise thereof, a bar point in said slot extending substantially throughout tbevlength of-said slot, said slot vbeing formed by two opposed .side lbar --parts and means iixedly mounting said point in said slot.

2. A `distributor box l.bar comprisingltwo elongated side K members, a bar point disposed between said members of a ,length .to project ,at one end, each member .and said point having transverse apertures for mating relation, and means traversing aligned apertures for clamping said members and point as a unitary box Ibar.
